ANSWER: This is fuligo septica, common name is dog vomit slime mold or scrambled egg slime mold. See here and here for more info.
Does anybody know what this is? It grew overnight in the sheet mulch. It looks solid but is the consistency of cream of wheat. By late afternoon it had dried to a thin red slab. It's sort of weird!
What is it?
Is its presence a good sign or a bad sign?
Should I leave it in the sheet mulch or remove it?
